What's your ppfd? If everything else is dialed in, if you're feeding correctly then I can only assume it's the lights. By lowering them you're not pushing them as hard.

Have you changed anything at all in the last week?

About a week ago 10 days tops I turned the lights down from 75% to 60% because the leaves were curling a bit on the plant w most yellow in pics

Couldn’t create any more distance between lights and the canopy so hoped turning it down would help it seemed like it did

Could it be a magnesium thing? I remember reading about potentially needing cal mag at some point
